0.0 Context Setting It’s Tuesday, 28 July, 2026 in Portland, Oregon. My brain is mush. 0.1 Events: How People Work, Live! How People Work, Live! is the live show about how to people. It’s based on my How People Work , my workshop that helps teams deliver better, faster, which itself is built on my last 20 years of working in tech. Each show I’m joined by a very special guest and any number of interesting people (that’s you) to find out how to get hard results by learning and app...

The perfect equipment set 2026-07-28 19:30 People often ask me what I actually use, day to day, to do the things I write about here. The honest answer is: not much. Four devices, a couple of cables, and a strong opinion about each one. This is that list, and why each item earns its place. I am not interested in the "latest and greatest". I am interested in a set that fits together, lasts, and does not quietly send my life to three different data brokers. So here it is, my perfect equipment...

Go’s proposal to allow examples with any signature was accepted on July 8. Today, an example must look like func ExampleXxx() . go/doc skips the function as soon as it sees a parameter or result. The example doesn’t appear in go doc or on pkg.go.dev. The restriction comes from the two jobs an example can do: appear in documentation and run as a test. The test behavior starts when the function has a trailing // Output: comment. The generated test harness can call ExampleXxx() ...

In his essay on Salvador Dali, Orwell argued that because Dali was a repulsive human being, the right wouldn’t admit that he was a great artist; conversely, because he was a great artist, the left wouldn’t admit he was a repulsive human being. I’m seeing the same thing with AI: because it’s unethical, one side won’t acknowledge that it’s useful, but because it’s useful, the other side won’t acknowledge that it’s unethical. Time to make another cup of tea… In his essay on S...

Research report · Internet Archive holdings · 26 July 2026 Short answer: the memex itself was never built — not even a lab prototype. But Bush spent a decade building and funding its component machines, two of which were real, and one of which was delivered to the U.S. Navy. This report traces exactly how far each piece got, from sources in the Internet Archive’s own scanned collections. §1 What the memex was, and where it was only ever ink Bush described the memex publicly just o...

When your program asks for memory that is not in cache, the processor has to go to RAM. That trip costs on the order of 100 nanoseconds. On a 3 GHz core, that is about 300 cycles of doing nothing. Memory latency has not improved in ten years. The 2016 Broadwell answers a random access in 100 ns. The 2025 Turin, with DDR5-6400 and every advantage of a decade of progress, takes 140 ns. It got worse. The good news is that a modern core does not have to sit still. It can issue a second request b...

When you’re on fire, problems are transparent: they’re solved simply by the act of looking at them. Even complicated layers of multiple problems can simply be glanced through like stacked panes of glass. But nobody can work that way all the time. This is a common pitfall for smart engineers. Accustomed to being able to immediately intuit the solution, the first time they run into a problem they can’t do this to is a disaster. It doesn’t even have to be a hard problem, just a problem wh...

Subagents get justified by time saved and parallel execution, but Rahul Garg explains that's not what matters most. Every token in the orchestrator's context is competing for its attention, and the real value of a subagent is what it keeps out of that context. Subagents should be treated as a tool for protecting the orchestrator's working memory, offloading reasoning it doesn't need to hold onto. Doing this well means giving the orchestrator explicit ground ...

Originally published on Rails At Scale . We recently enabled a really cool feature in ZJIT that makes it feel like a Real Compiler™: the inliner! We’ll write more about it soon. In this post, we’ll talk about one excellent concrete benefit we are already seeing and how it optimizes blocks in pretty much every Ruby program. I’ll start off with a refresher on how blocks work in the Ruby interpreter, then show you how ZJIT understands and optimizes that bytecode, and then show you th...

Amodei in his latest blog post wrote a mix of agreeable things and things that I believe misrepresent where the real risk of AI is located. I want to focus my attention on why, among all the risks, open weight models constitute the mildest one. I write these words as a person who strongly believes AI may be very dangerous in the near future: 1. Exactly like what happened during the OpenAI / HF incident (which was a joke, but focus on the modalities, not the outcomes), the first serious AI inc...

Introduction In the Livelymerge project, Dan Ingalls, Peter Van Hardenberg, and I (Alex Warth) are building a Lively Kernel-like system whose heap — every object, class, and method — is an Automerge document. The pitch, from the first note in this series, was that this would give us merges “for free”: multiple users share the same object memory, work on it concurrently (even offline), and Automerge reconciles everything. I also wrote that merging the state of a live system is a non...

In a recent post I gave intuition for the sparse Cholesky elimination tree by appealing to the task DAG and showed how it could be compressed into a tree in the sparse case. That post also showed how to use and compute the tree. Here I take a narrower and more conventional route: I start from a naive symbolic translation of right-looking Cholesky, identify the structural work it repeats, and show how retaining only the first later row affected by each factor column naturally produces the elimi...

TAIPEI (July 29, 2026) — Shield AI and Thunder Tiger Corp. today announced the successful completion of Hivemind’s first multi-asset autonomous teaming demonstration on water, validating Shield AI’s Hivemind AI pilot aboard Thunder Tiger SeaShark unmanned surface vessels (USVs) in a coordinated mission. During the demonstration in Pingtung, Taiwan, Thunder Tiger’s SeaShark 600 and SeaShark 800 USVs equipped with Hivemind autonomously executed a coordinated intelligence, surveillance, a...

Welcome to Austin’s Nerdy Things, where we send punctuation to a frontier AI model 649 times and take notes on what crawls out. The night of July 27th, a weird Claude behavior was making the rounds on X. A thread from @merlindru (187K views) flagged a strange Opus 5 failure mode around a specific text, and @fdosmither followed up with a sharper observation about a related trigger: a spaced - - - divider seemed to confuse Claude into treating the user’s turn as unfinished — his s...

There is nothing I hate more than doing self-promotion. The idea of talking about something I’m doing, I’ve done, or I'm going to do makes my skin crawl. But the opposite, promoting things other people are doing—especially friends—fills me with so much joy that I’ll never miss out on the opportunity of doing it. And that’s why I’m excited to let you know that my longtime friend Mattia is about to embark on another of his trips, this time touching Taiwan, South Korea, and Japan,...

Today, the world is made of people. This gives people a tiny measure of leverage: factory workers can sabotage the machines and halt production, truck drivers can strike and halt the entire economy, the police can stand back and let a protest topple the government , the military can mutiny . This sets a limit to how much the powerful can abuse the powerless: no matter how powerful someone is, how much money they have, how many divisions they command, they are still embedded in a society. They ...

Let's say there is a statement in math T that you wonder whether it's true or false.  You may even make a conjecture of which way it goes. Do you have a rooting interest?  I may think T is true, but if someone proves T or proves NOT(T) my main concerns are (1) can I understand the proof ? (2) is the proof interesting? Paul Erdos posed the sum-product conjecture which was recently proven false (by humans!).  I blogged about it  here . I wondered whether Paul Erdos would be happy with how it t...
